Table 1. The Ten-Point Surgical Apgar Score.

The Surgical Apgar Score is calculated at the end of an operation, from the estimated blood loss, lowest mean arterial pressure and lowest heart rate entered in the anesthesia record during the operation. The score is the sum of the points from each category.

	0 points	1 point	2 points	3 points	4 points
Estimated blood loss (mL)	>1000	601–1000	101–600	≤100
Lowest mean arterial pressure (mm Hg)	<40	40–54	55–69	≥70
Lowest heart rate (beats per min)	>85*	76–85	66–75	56–65	≤55*

^*Occurrence of pathologic bradyarrhythmia, including sinus arrest, atrioventricular block or dissociation, junctional or ventricular escape rhythms, and asystole also receive 0 pts for lowest heart rate
